No. 002780018

  Here, in general, it is an easy task to pour water into a container such as a cup and stop the water injection at an appropriate water level before the poured water overflows from the cup. However, it is not easy for a visually handicapped person who cannot visually detect a rise in water level to stop water injection at an appropriate water level.

  The cup for visually impaired persons disclosed in Patent Document 1 is configured such that when water is poured up to the mounting position of the electronic device, a switch provided in the electronic device is pushed by a piece of wood that floats due to the buoyancy of the water. Is configured to sound. Thereby, the cup for visually impaired persons can notify by sound that a predetermined amount or more of water has been poured into the cup. As a result, the user can know the timing of stopping the water injection before the water overflows from the container, so that the water injection can be stopped at an appropriate water level without using vision.

  However, the above-mentioned cup for the visually handicapped person generates a sound by an electronic device, and therefore requires a battery as a power source. For this reason, periodic battery replacement work is required, which is inconvenient for the visually impaired.

  In addition, the cup for the visually impaired is a product limited to the shape of the cup. For this reason, the cost increases in order to individually provide the voice notification function to various containers such as cups and pans of other shapes that the visually handicapped person desires to use.

  The present invention provides a water level notification device that can notify by sound that a predetermined amount or more of water has been poured into a container without requiring a power source, and can be applied to containers of various shapes. With the goal.

The water level notification device according to the present invention is a water level notification device that is placed on the opening edge of a container capable of storing liquid and that notifies that a predetermined amount of liquid has been poured into the container by generating sound, A holding part placed on the opening edge of the container, a connection part provided with the holding part, an inner part accommodated inside the container, a connection part provided with the holding part, and located outside the container. And an outer portion that is displaced in accordance with the upward displacement of the tip of the inner portion due to the buoyancy that acts from the liquid poured into the liquid , and a sounding portion that is a part of the outer portion. The sounding part strikes the outer wall of the container by moving according to the displacement of the outer part when a predetermined amount of liquid is poured into the container with the holding part placed on the opening edge of the container. To do.

  Since the water level notification device according to the present invention is placed on the opening edge of the container, it can emit sound by being displaced by buoyancy acting from the liquid poured into the container. It can be applied to the container, and it can be notified by sound that a predetermined amount of water has been poured into the container without requiring a power source.

-First embodiment-
Fig.1 (a) shows the perspective view which looked at the water level alerting | reporting instrument 100 of this embodiment from diagonally upward, FIG.1 (b) mounts the water level alerting | reporting instrument 100 on the opening edge of containers 5, such as a cup. It represents the state.

  The water level notification device 100 includes a holding part 1, an inner part 2 provided continuously with the holding part 1, an outer part 3 provided continuously with the holding part 1 and the inner part 2, and a substantially distal end portion of the outer part 3. And a sound generation unit 4 provided in In addition, it is preferable that the material which forms the water level alerting | reporting instrument 100 is a material with specific gravity lighter than water, such as woods, such as a cypress, and plastics, such as a polypropylene.

  Note that “pronunciation” used in the present specification means that a sound is emitted. Further, the “sound generation unit” is not limited to a part that emits a sound by itself, but includes a part that generates a sound by hitting another member.

  When the water level notification device 100 is used, the water level notification device 100 is placed on the opening edge of a container such as a cup via the holding portion 1 (see FIG. 1B). The water level notification device 100 according to the present embodiment is composed of one continuous material. However, each part of the water level notification instrument 100 is defined as follows. That is, in a state in which the water level notification device 100 is placed on the opening edge of the container 5, the part that contacts the opening edge of the container 5 is the holding part 1, the part that is accommodated inside the container 5 is the inner part 2, and the outside of the container 5 The portion located at is defined as the outer portion 3. The sounding portion 4 indicates a region on the inner side 2 side of the substantially distal end portion of the outer side portion 3, in other words, a region on the outer wall side of the container 5 of the outer side portion 3 in a state where the water level notification device 100 is placed on the container 5.

  The water level notification device 100 is configured such that the inner side portion 2 and the outer side portion 3 are balanced like a so-called “frozen” with the holding portion 1 as a fulcrum. Thus, the user simply places the water level notification device 100 on the opening edge of the container 5, and the water level notification device 100 is held at the opening edge of the container 5 with the outer portion 3 not in contact with the outer wall of the container 5. .

  The water level notification device 100 configured in this way is placed on the opening edge of the container 5 and when a liquid (for example, water) is poured into the container 5, the container 5 has a predetermined volume less than the volume of the container 5. The timing when the liquid amount is poured can be notified by sound.

  FIG. 2 is a diagram for explaining the operation of the water level notification device 100 when the container 5 is notified by sound that a predetermined amount of water has been poured.

  The user first places the water level notification instrument 100 on the opening edge of the container 5 before pouring water into the container 5. At this time, the water level notification device 100 is held at the opening edge of the container 5 at least in a state where the sounding portion 4 is not in contact with the outer wall of the container 5 (see FIG. 1B).

  Then, when the user pours water directly using a pot or the like, or when water injection into the container 5 is started by twisting the faucet, the water level of the liquid stored in the container 5 gradually increases. (Arrow A in FIG. 2).

  As water continues to be poured into the container 5, the raised water level comes into contact with a part of the inner portion 2 at a certain timing, and continues to rise. If it does so, the inner side part 2 which contacted the predetermined amount of water will be displaced by the effect | action of the buoyancy of water, will be pushed up by water and will raise (arrow B).

  Then, since the outer side part 3 is continuous with the inner side part 2, it is displaced downward as the inner side part 2 rises. The sounding portion 4, which is a part of the substantially distal end portion of the outer portion 3, moves downward along a substantially arc-shaped trajectory with the holding portion 1 as a fulcrum as the inner portion 2 rises, and the outer wall of the container 5 (Arrow C). As a result, the sound generation unit 4 strikes the outer wall of the container 5, and thus a hitting sound is generated when the sound generation unit 4 collides with the outer wall of the container 5.

  Thereby, the water level notification instrument 100 can notify the user that a predetermined amount of water has been poured into the container 5 by sound.

  Then, the modification (water level notification instrument 101) of the water level notification instrument 100 of 1st Embodiment is demonstrated. The water level notification device 100 is not limited to the configuration described in FIGS. 1 and 2, and may have a configuration as shown in FIG. 3, for example.

  FIG. 3 is a diagram for explaining the water level notification instrument 101. The water level notification device 101 includes a holding part 1, an inner part 2, an outer part 3, a sounding part 4, and a buoyancy body 6 provided on the inner part 2. Unlike the water level notification device 100, the water level notification device 101 does not necessarily need to be composed of one continuous material. As suggested in FIG. 3, in the water level notification device 101, the holding portion 1, the inner portion 2, and the outer portion 3 are made of the same material, but the sounding portion 4 and the buoyancy body 6 are different from each other. It is formed of the material of. Moreover, the holding | maintenance part 1, the inner side part 2, and the outer side part 3 do not need to be formed with the raw material smaller than the specific gravity of water, for example, may be formed from the raw material with larger specific gravity than water, such as a metal and glass.

  The buoyancy body 6 provided in the inner part 2 is formed of a material having a specific gravity smaller than that of water, such as polypropylene or foam. For this reason, the inner side part 2 provided with the buoyancy body 6 acts from the water which contacted similarly to the inner side part 2 of the water level alerting | reporting instrument 100, when the buoyancy body 6 contacts the water poured into the container 5. Due to the buoyancy, it can be displaced upward according to the rise of the water level.

  In addition, the buoyancy body 6 may be comprised so that adjustment of the attachment position in the inner side part 2 is possible. For example, as shown by an arrow D in FIG. 3, the buoyancy body 6 in the present modification is slid up and down from the distal end side of the inner portion 2 accommodated in the container 5 to the holding portion 1 side. be able to. Thereby, since the water level when the water poured into the container 5 and the buoyant body 6 come into contact with each other can be adjusted, it is stored in the container 5 when notifying the user of the timing to stop pouring water. The amount of liquid to be adjusted can be adjusted.

  The sounding unit 4 of the water level notification instrument 101 is a bell. The bell is provided at the tip of the outer portion 3 in FIG. With this configuration, the bell collides with the outer wall of the cup by moving the outer portion 3 according to the displacement of the inner portion 2 as in the water level notification instrument 101. Since the bell rings due to the impact related to this collision, the water level notification device 101 can generate a louder sound than the water level notification device 100. In addition, the bell provided in the water level notification device 101 is not necessarily provided at the tip of the outer portion 3, and may be a position other than the tip portion of the outer portion 3 as long as it is the outer portion 3. In this case, the bell included in the water level notification device 101 is generated by the vibration of the bell due to an impact when a part of the outer portion 3 collides with the outer wall of the cup.

  As described above, the water level notification device 100 according to the first embodiment is placed on the opening edge of the container 5 capable of storing liquid, and generates a sound to notify that a predetermined amount of liquid has been poured into the container 5. It is a water level notification device and is connected to the holding unit 1 placed on the opening edge of the container 5, connected to the holding unit 1, and accommodated inside the container 5, and connected to the holding unit 1 And an outer portion 3 that is located outside the container 5 and that displaces as the tip of the inner portion 2 is displaced upward by buoyancy acting from the liquid poured into the container 5. And a sound generation unit 4 that generates sound by moving according to the displacement of the sound.

  Further, according to the water level notification device 100 of the first embodiment, the sounding unit 4 is a part of the outer portion 3, and the container 5 is placed in the state where the holding unit 1 is placed on the opening edge of the container 5. When a fixed amount of liquid is poured, the outer wall of the container 5 is hit and pronounced by moving according to the displacement of the outer portion 3. Thereby, the water level notification device 100 can notify by sound that a predetermined amount of liquid has been stored in the container 5. As a result, the user can know that a predetermined amount of liquid has been stored in the container 5 without having to visually confirm the water level.

  For this reason, for example, even when the user is a visually handicapped person and pours the liquid into the container 5 himself, it is possible to appropriately know the timing to stop water injection. Can be completed. Further, when the liquid to be poured is hot water, it is possible to avoid the risk of burns caused by overflowing hot water.

  Also, for example, even if the user is a cook working at a restaurant, etc., even if water is stored in a large pan or a small cylinder, the water level notification will be given after the faucet plug is loosened and water injection into the large cylinder is started. It is not necessary to keep an eye on the water level until the instrument 100 sounds. For this reason, since other operations can be performed during pouring, the operation efficiency of a cook or the like can be improved.

  Further, a water level notification device 101 which is a modification of the first embodiment includes a buoyancy body 6 on the inner side 2. For this reason, since the specific gravity of the whole inner part 2 provided with the buoyancy body 6 should just be a magnitude | size which can be displaced by the effect | action of the buoyancy of water, the inner part 2 can be formed with materials, such as iron with larger specific gravity. It becomes possible.

  Moreover, in the water level notification instrument 101 which is a modified example of the first embodiment, the sound generation unit 4 is a bell. For this reason, since the sound of a bell can be emitted when the sound generating unit 4 and the container 5 collide, a larger sound can be emitted as compared with the water level notification instrument 100.

-Second Embodiment-
Next, the water level notification instrument 200 of the second embodiment will be described. The water level notification device 200 is particularly different from the water level notification device 100 of the first embodiment in the configuration of the sound generation unit 4.

  FIG. 4A shows a perspective view of the water level notification device 200 as viewed from obliquely above, and FIG. 4B shows a side view of the state in which the water level notification device 200 is placed on the container 5.

  The water level notification device 200 includes a holding part 1, an inner part 2 provided continuously with the holding part 1, an outer part 3 provided continuously with the holding part 1 and the inner part 2, and a sound generation provided on the outer part 3. Part 4. The sound generation unit 4 includes a sounding unit 40, a support shaft 41 having the sounding unit 40 at one end, and a rotation support unit 42 provided on the outer side 3 and rotatably connected to the other end of the support shaft 41. Consists of The outer portion 3 is held on the opening edge of the container 5 so that the sound hitting portion 40 or the support shaft 41 leans, so that the sound hitting portion 40 can be held upward with the rotation support portion 42 as a fulcrum. It has a slope that can be done.

  When the water level notification device 200 is used, the water level notification device 200 is placed on the opening edge of the container 5 via the holding unit 1 (see FIG. 4B). At this time, the user sets so that the sound hitting part 40 and the support shaft 41 constituting the sounding part 4 are positioned above the rotation support part 42. In this state, the water level notification device 200 maintains the stationary state by the sounding portion 40 or the support shaft 41 leaning on the inclination of the outer portion 3, and at least the outer portion 3 of the container 5 is maintained with the holding portion 1 as a fulcrum. The container 5 is held at the opening edge of the container 5 without being in contact with the outer wall. The inclined surface is not limited to a straight line (plane) as illustrated, and may have a curved portion.

  FIG. 5 is a diagram for explaining the operation of the water level notification instrument 200. FIG. 6 is a diagram for explaining an operation that the water level notification device 200 generates a sound. 6A is a side view of the water level notification device 200, and FIG. 6B is a diagram for explaining a mode in which the water level notification device 201, which is a modification of the water level notification device 200, sounds. is there.

  Water injection into the container 5 in a state where the water level notification device 200 set so that the sound hitting part 40 is positioned above the rotation support part 42 is placed on the opening edge of the container 5 (see FIG. 4B). Is started, the water level of the liquid stored in the container 5 gradually rises (arrow A).

  When the water injection is continued, the raised water level comes into contact with a part of the inner portion 2. As the water level continues to rise, the inner portion 2 that has come into contact with a predetermined amount of water is pushed up by the buoyancy acting from the water (arrow B). Then, since the outer part 3 is provided continuously with the inner part 2, it moves downward as the inner part 2 rises and approaches the outer wall of the container 5 (arrow C).

  When water is further poured into the container 5, the inclination of the outer portion 3 becomes vertical, and when water is further poured, the inclination is projected from the sounding portion 40. In the meantime, the center of gravity of the sound hitting portion 40 and the support shaft 41 located on the container 5 side with respect to the rotation support portion 42 moves outward in the reverse direction from the container 5 side as the outer portion 3 moves. Then, when the sound hitting part 40 and the support shaft 41 that have maintained their posture by leaning on the inclination of the outer side part 3, the center of gravity of the sounding part 40 and the support shaft 41 are separated outward in the reverse direction on the container 5 side from the rotation support part 42. Thus, it rotates downward with the rotation support part 42 as a fulcrum (arrow E).

  As a result, in the water level notification device 200, the sound hitting portion 40 collides with a part of the outer side portion 3 to generate a sound (see FIG. 6A). If the outer portion 3 and the sounding portion 40 are made of wood, a timbre like xylophone can be generated by selecting wood. Further, if at least a part of the sound hitting part 40 is made of metal and a part where the metal part of at least the sound hitting part 40 of the outer part 3 collides is made of metal, a tone like a koto is generated. be able to. That is, the water level notification instrument 200 can change the tone color to be generated by changing the material of the portion where the sound hitting portion 40 and the outer portion 3 collide with each other.

  Next, a water level notification instrument 201 as a modification of the water level notification instrument 200 will be described. The water level notification instrument 201 is different from the water level notification instrument 200 in that a rotation support portion 42 is provided at the distal end portion of the outer portion 3 (see FIG. 6B). When the sound generating unit 4 is configured in this way, the sound-sounding unit 40 is configured such that when the inclination of the outer part 3 becomes an angle at which the sound-sounding part 40 cannot be supported, the rotation support part 42 is used as a fulcrum. It rotates without colliding with the part (arrow E). As a result, the sound hitting portion 40 is sounded by colliding with a part of the outer wall of the container 5.

  In this manner, the water level notification devices 200 and 201 according to the second embodiment can notify the user with a sound that a predetermined amount of water has been poured into the container 5. In addition, the sound-sounding part with respect to the amount of water stored in the container 5 by changing the angle of inclination of the outer part 3 that supports the sound-sounding part 40 or changing the length of the inner part 2 from the holding part 1. 40 rotation start timings can be adjusted. For example, if the length of the inner portion 2 from the holding portion 1 is shortened, the amount of water in contact with the water to be poured and the inner portion 2 increases, so the amount of water in the container 5 during sound generation increases.

  Then, the other modification of the water level alerting | reporting instrument 200 of 2nd Embodiment is demonstrated. Hereinafter, with reference to FIG. 7, each modification (water level alerting | guidance instruments 202-204) demonstrates the difference from the water level alerting | reporting instruments 200 and 201 for every modification.

  FIG. 7A is a diagram for explaining the water level notification instrument 202. The water level notification device 202 is characterized in that the rotation support portion 42 is a hole provided so as to penetrate in the lateral direction of the outer portion 3. The support shaft 41 of the water level notification device 202 is formed in a substantially U shape or a square shape by a linear member such as a wire, and one end of the support shaft 41 is rotatably attached to the rotation support portion 42. And the sound hitting part 40 is attached to the other end of the support shaft. Even in the water level notification device 202 configured as described above, the outer side portion 3 moves in the same manner as described for the water level notification devices 200 and 201 in accordance with the movement of the inner side portion 2 due to the buoyancy of water in the container 5. Therefore, when a predetermined amount of water is poured into the container 5, the sound hitting unit 40 rotates about the rotation support unit 42 as a fulcrum.

  Here, the support shaft 41 of the water level notification instrument 202 is made of a wire, and has a substantially U-shape or quadrangular shape that is wider than the length of the outer portion 3 in the short direction. Therefore, if the distance from the rotation support portion 42 to the tip of the outer portion 3 is shorter than the distance from the rotation support portion 42 to the sound hitting portion 40, the outer portion 3 passes through the inside of the support shaft 41. The moved sounding portion 40 strikes the outer wall of the container 5 beyond the outer portion 3. On the other hand, if the distance from the rotation support part 42 to the tip of the outer part 3 is longer than the distance from the rotation support part 42 to the sounding part 40, the rotated sounding part 40 will partly move the outer part 3. Tap. Thereby, the water level notification instrument 202 can notify the user that a predetermined amount of water has been stored in the container 5 with sound.

  FIG. 7B is a diagram for explaining the water level notification instrument 203. The water level notification device 203 is characterized in that the sounding unit 4 is configured to be removable from the outer side unit 3. In the example shown in the figure, the sounding portion 4 is provided on a ring-shaped member (ring-shaped member) made of an elastic body such as rubber. Then, the sounding portion 4 is fixed to the outer portion 3 by inserting the outer portion 3 into the ring-shaped member. Thereby, for example, a plurality of sound generating parts 4 having different materials or the like of the sound hitting part 40 are prepared, and the sound generating part 4 to be attached is selected for one main body composed of the holding part 1, the inner part 2, and the outer part 3. The timbre etc. can be changed.

  FIG. 7C is a diagram for explaining the water level notification instrument 204. The water level notification device 204 is characterized in that the sound hitting unit 40 is constituted by a bell. More specifically, the water level notification device 204 includes a holding unit 1, an inner part 2 provided continuously with the holding part 1, an outer part 3 provided continuously with the holding part 1 and the inner part 2, and an outer side. And a sound generation unit 4 provided in the unit 3. The sound generation unit 4 includes a bell as the sounding unit 40, a support shaft 41 having the sounding unit 40 at one end, and a rotation support unit that rotatably connects the other end of the support shaft 41 to the outer side unit 3. 42.

  Even when the water level notification device 204 is used, the user places the water level notification device 204 on the opening edge of the container 5, and the sounding portion 40 and the support shaft 41 are in contact with the rotation support portion 42. Set so that it is positioned above. When a predetermined amount of water is poured into the container 5, the outer portion 3 moves according to the movement of the inner portion 2 due to the buoyancy of the water in the container 5, so that a predetermined amount of water is poured into the container 5. At that time, the sound hitting portion 40 rotates with the rotation support portion 42 as a fulcrum (see FIG. 4). At this time, since the sound hitting unit 40 included in the water level notification device 204 is a bell, the impact when the sound hitting unit 40 collides with the outer wall of the container 5 or a part of the outer side 3 or the sound hitting unit 40 is provided. The hitting portion 40 generates a sound by the impact when the support shaft 41 collides with a part of the outer portion 3 and the rotation stops. Thereby, the water level notification instrument 204 can notify that a predetermined amount of water has been poured into the container 5 with the tone of a bell.

  Since the sound hitting portion 40 is a bell, as described with reference to FIG. 6, when the sound hitting portion 40 rotates, at least one of the sound hitting portion 40 and the support shaft 41 is directly on the container 5 or the outer portion 3. It need not be configured to collide. That is, in the second embodiment, the sounding portion 40 constituted by the bell does not collide with the outer wall of the container 5 or a part of the outer side portion 3 when the sounding portion 40 and the support shaft 41 are rotated. However, it can also be pronounced by vibrating when the bell falls due to rotation.

  As described above, according to the water level notification devices 200 and 201 of the second embodiment, the sound generation unit 4 is provided at the support shaft 41 whose one end is rotatably attached to the outer portion 3 and the other end of the support shaft 41. And a sound hitting unit 40. The sound hitting part 40 is a case where a predetermined amount of liquid is poured into the container 5 in a state where the holding part 1 is placed on the opening edge of the container 5 and the sound hitting part 40 is located above the support shaft 41. Is rotated downward in accordance with the displacement of the outer portion 3, and sounds by hitting the outer wall of the container 5 or a part of the outer portion 3. Thereby, the water level notification instrument 200 can notify with a loud sound that a predetermined amount of liquid has been stored in the container 5.

  Moreover, according to the water level notification instrument 204 which is a modification of the second embodiment, the sounding unit 4 is provided at the other end of the support shaft 41 and the support shaft 41 whose one end is rotatably attached to the outer portion 3. A bell is provided as the hitting portion 40. The bell is placed outside when a predetermined amount of liquid is poured into the container 5 in a state where the holding part 1 is placed on the opening edge of the container 5 and the sounding part 40 is positioned above the support shaft 41. According to the displacement of the part 3, it is rotated downward and pronounced. Thereby, it can be notified by the sound of a bell that a predetermined amount of water has been poured into the container 5.

  Next, the water level notification instrument 300 of the third embodiment will be described. The water level notification instrument 300 is particularly different from the above-described water level notification instrument in the configuration of the outer portion 3 and the sounding portion 4.

  FIG. 8A is an external view showing a side surface of the water level notification device 300. FIG. 8B is a side sectional view of the water level notification device 300. FIG.8 (c) is side surface sectional drawing for demonstrating the aspect which the water level alerting | reporting instrument 300 produces.

  As shown in FIG. 8A, the water level notification device 300 includes a holding part 1, an inner part 2 provided continuously with the holding part 1, and an outer part 3 provided continuously with the holding part 1 and the inner part 2. With. And as shown in FIG.8 (b), the outer side part 3 is equipped with the cavity part 7 which can accommodate the spherical member as the sounding part 40 in the inside. The cavity portion 7 is an internal space formed continuously from the end portion (bottom portion 72) located on the opposite side of the inner portion 2 to the vicinity of the holding portion 1 in the outer portion 3. Near the holding portion 1 of the cavity portion 7, a base portion 71 is provided that can hold the sound hitting portion 40 in a state where the water level notification device 300 is placed on the opening edge of the container 5.

  When the water level notification device 300 is used, the water level notification device 300 is placed on the opening edge of the container 5 via the holding unit 1 as described with reference to FIG. At this time, the sound hitting portion 40 accommodated in the hollow portion 7 is held on the base portion 71. When water injection into the container 5 is started and the water level of the liquid stored in the container 5 rises, the raised water level comes into contact with a part of the inner portion 2. When the water level further rises, the inner part 2 that has come into contact with a predetermined amount of water is displaced by the action of buoyancy and is pushed up by the water and rises (arrow B).

  Since the outer part 3 is provided continuously with the inner part 2, the outer part 3 moves downward with the holding part 1 as a fulcrum as the inner part 2 rises, and the tip of the outer part 3 approaches the outer wall of the container 5. (Arrow C). As a result, the mounting surface 40 of the base 71 is gradually inclined according to the movement of the outer portion 3.

  And if the inclination of the base part 71 reaches the angle which cannot hold | maintain the sounding part 40, the sounding part 40 will fall in the cavity part 7 (arrow E). As a result, the sound hitting portion 40 collides with the bottom portion 72 and generates a sound. Thereby, the water level notification device 300 can notify by sound that a predetermined amount of water has been poured into the container 5.

  In addition, the shape of the base part 71 is not specifically limited. The pedestal 71 can hold the sound hitting unit 40 in the vicinity of the holding unit 1 or in a position away from the bottom 72 by a predetermined distance in a state where the water level notification instrument 300 is placed on the opening edge of the container 5. It can be configured so that the sound hitting portion 40 falls before the tip of the outer portion 3 contacts the outer wall of the container 5.

  As described above, according to the water level notification device 300 of the third embodiment, the outer portion 3 has the hollow portion 7 inside, and the hollow portion 7 is placed on the opening edge of the container 5 with the bottom portion 72 and the holding portion 1. And a base portion 71 on which a spherical member as the sound generating portion 4 can be placed. The sound generation unit 4 is configured such that when the holding unit 1 is placed on the opening edge of the container 5 and the sound generation unit 4 is placed on the platform 71, a predetermined amount of liquid is poured into the container 5. By dropping the cavity portion 7 according to the displacement of the outer side portion 3, the bottom portion 72 is hit and pronounced. Thereby, the water level notification device 300 can notify the user with a sound that a predetermined amount of water has been stored in the container 5.

-Fourth embodiment-
Next, the water level notification instrument 400 of the fourth embodiment will be described. The water level notification device 400 is particularly different from the above-described water level notification device in the shape of the holding unit 1.

  FIG. 9 is a side view showing the shape of the water level notification instrument 400, and shows a state in which the water level notification instrument 400 is placed on the container 5 before water injection is started. As shown in FIG. 9, the holding unit 1 of the present embodiment includes a first holding unit 1 a in a state where the first holding unit 1 a and the first holding unit 1 a are placed on the opening edge of the container 5. Connecting portion connecting the second holding portion 1b, the first holding portion 1a, and the second holding portion 1b, located on the inner side 2 side of the first holding portion 1a. And 1c.

  Before injecting water into the container 5, the water level notification device 400 supports the holding part 1 a located at the lower stage among the holding parts 1 formed with a step difference in the vertical direction while being placed on the container 5. Held in the container 5. That is, the water level notification device 400 is configured such that the inner portion 2 and the outer portion 3 are balanced with the holding portion 1a as a fulcrum.

  FIG. 10 is a diagram for explaining an aspect in which the water level notification instrument 400 generates a sound. Hereinafter, a description will be given with reference to FIG.

  FIG. 10a is a diagram illustrating a state in which the holding by the holding unit 1a has reached the limit after the start of water injection. Unlike the holding unit 1 of the first embodiment, the holding unit 1 a is set to have a narrow width in the vertical direction with respect to the opening edge of the container 5. Accordingly, as described above in the description of the first embodiment, the water level in the container 5 rises due to water injection, and the inner part 2 is displaced by the action of buoyancy, so that the holding part 1a with respect to the opening edge of the container 5 is displaced. When the inclination changes, the contact area between the holding portion 1a and the opening edge of the container 5 decreases. And if a water level rises further, it will become impossible to hold | maintain the water level alerting | reporting instrument 400 only with the frictional force which concerns on the contact area of the holding | maintenance part 1a and the opening edge of the container 5. FIG.

  As a result, the water level notification device 400 is held by the second holding portion 1b (see FIG. 10b) beyond the connecting portion 1c from the state where the first holding portion 1a is held at the fulcrum (see FIG. 9). To see).

  As shown in FIG. 10 b, the water level notification device 400 is configured such that a part of the outer portion 3 is in contact with the outer wall of the container 5 while being held by the second holding portion 1 b. Therefore, when a predetermined amount of water is poured into the container 5, the water level notification device 400 moves at a stroke from the state held by the first holding unit 1 a to the state held by the second holding unit 1 b. Accordingly, the outer part 3 moves vigorously, so that a part of the outer part 3 can hit the outer wall of the container 5. As a result, the water level notification device 400 can notify that the predetermined amount of water has been poured into the container 5 with a louder sound than the water level notification device 100.

  As described above, according to the water level notification device 400 of the fourth embodiment, the holding unit 1 includes the first holding unit 1 a and the first holding unit 1 a placed on the opening edge of the container 5. The second holding portion 1b is located above the holding portion 1a and is located on the inner side 2 side of the first holding portion 1a. A part of the outer side portion 3 is formed by the first holding portion 1a. When a predetermined amount of liquid is poured into the container 5 in a state of being placed on the opening edge of the container 5, the second holding portion 1b is displaced to a state of being placed on the opening edge of the container 5, As the outer part 3 moves, the outer wall of the container 5 is hit and pronounced. As a result, it is possible to produce a louder sound than in the first embodiment.

  The present invention is not limited to the above-described embodiment. For example, the water level notification device 100 according to the first embodiment has been described as being configured so that the inner portion 2 and the outer portion 3 are balanced like the balance with the holding portion 1 as a fulcrum. However, the inner portion 2 and the outer portion 3 of the water level notification device according to the present invention do not necessarily have to be balanced with one holding portion as a fulcrum as in the case of the balance, and the center of gravity of the inner portion 2 and the outer portion 3 is held. Assuming that it is below the portion 1, the holding portion and the opening edge may be placed in contact with each other at a plurality of locations. Further, assuming that the outer portion 3 does not contact the outer wall of the container 5 and that the outer portion 3 is displaced in accordance with the displacement of the inner portion 2, the outer portion and the inner portion are always in a balanced state. There is no need, for example, the inner part 2 may be in contact with the inner wall of the cup.

  Moreover, when the inner side part 2 is immersed in the water stored in the container 5, the apparent weight of the inner side part 2 applied to the immersed part varies depending on the buoyancy acting from the water. For this reason, when the balance between the weight of the inner portion 2 and the weight of the outer portion 3 changes, the inner portion 2 may rise and the outer portion 3 may move downward. That is, the inner portion 2 may be displaced by buoyancy acting from water even if its specific gravity is not less than water. Therefore, the specific gravity of the inner side part 2 does not necessarily need to be smaller than water, and may be larger than the specific gravity of water.

  Further, the holding portion 1, the inner portion 2, and the outer portion 3 are not necessarily provided continuously, and the inner portion 2 and the outer portion 3 operate as described above with respect to the water stored in the container 5. May be formed separately and connected to each other.

  Further, the buoyancy body 6 does not necessarily need to be formed of a material having a specific gravity smaller than that of water, and even if a material having a specific gravity of larger than that of water is used, the buoyancy body 6 may be hollow or the like as long as the overall specific gravity is smaller than that of water. good.

  Further, the water level notification device 400 is not necessarily required to be held in a state where the outer portion 3 and the outer wall of the container 5 are in contact with each other with the holding portion 1b as a fulcrum. That is, the outer part 3 moves vigorously and strikes the outer wall of the container 5 as it moves from the state held by the first holding part 1a to the state held by the second holding part 1b at a stroke. If possible, the outer portion 3 and the outer wall of the container 5 may be separated after sound generation.

  Note that the features according to the above-described embodiments and modifications may be applied in appropriate combination within a range where no contradiction occurs. For example, the water level notification device 200 according to the second embodiment includes a buoyancy body 6 as in a water level notification device 101 which is a modification of the first embodiment, and the inner portion 2 and the outer portion 3 are made of a material such as iron. May be formed.
